My .invention relates to closures for containers, its generalobject being that of pro desired an in which the tightly closing cover;

can instantly be attached; More particularly, my invention provides a container (or receptacle) and a cover member, provides the cover member with cover retaining means including portions disposed so as to be engaged by or disengaged from portions of the receptacle by a relative rotation of the cover with 4 respect to the receptacle, and provides simple means on the cover member for forcing the cover towards the receptacle after the said portions of the receptacle have [been engaged by the cover retaining means.

More particularly, my invention provides a receptacle'having a pair of lateral projections near its mouth, a cover for the receptacle, a thrust member movably mounted on the cover and provided with'portionsadapted to underhang the said projections, and

cam means for moving the thrust member with respect to the cover so as to force the cover against the container. Furthermore,

my invention provides a construction for this purpose in which the cam means can be mounted'on a-single member which connects the thrust member to the cover and which member may be tubular so as. to afford an outlet for thecontainer. Still further and w also more detailed objects'willappear from the following specification and from the ac- Fig. 1 is an elevat'on of apaint cup for a spraying appliance, showing this as embodyin my invention.

In constructing paint spraying appliances of the type in which the atomizer or spray appliance proper is mounted directly on a cup or other container, it has heretofore been difficult to combine a tight sealing of the -container with convenience in opening or' closincr the latter; The liquids used in such appliances usually are of a quick drying nature,-'so' that they will readily gum any threads on both'the cup and the cover, thereby Imaking it 'difiicult for the user to detach a cover which is secured to the container in the usual threaded manner. On the other hand, arrangements heretofore employed for insuring a tight seal between a cup or other container and a slip-on or telescoping cover have usually been both complicated and difficult of manipulation.

My present invention aims to overcome both of these sets of objections and aims to do so in a quite simple and inexpensive construction. Since my invention in its immediate commercial prospects is particularly applicable for use in connection with paint spraying apparatus, I am illustrating and describing it in a corresponding embodiment,

although I do not wish to be limited to any particularuse for what is here disclosed.

In the embodiment of the drawings, the

paint container includes an upwardly open receptacle 1 carrying a pair of pins 2 which extend diametrically of the receptacle and project outwardly from opposite sides of the receptacle at some distance below thetop or mouthend of the receptacle. The cover 3 for this receptacle '1 carries a. washer 4 which seats on the upper end of the receptacle, and the cover also has a downwardly directed peripheral flange 5 which telescopes over the month end of the receptacle. Extending through a central perforation in the cover 3 is a stem member (here shown as tubular) which has an annular shoulder 6 engaging the ber together constitute a rigid cover member.

The stem member also has a more ele vated cylindrical portion 9 which extends slidably through a corresponding perforatop of the'cup, and which also has a threaded portion 7 extending through tion in the center'of a yoke or thrust member 10. This yoke reaches beyond the op osite sides of the cover and has a pair of dbwn- ,wardly directed arms 11, each of which arms is equipped at its lower end with a hook 12 which opens circumferentially of the container and which hook has: a portion adapted to underhang one of the said pins 2.

The slidable extension; of the. tubular member. or riser stem through the yoke permits gravity to slide to yoke downwardly with respect tothe said stem and the cover. However, I preferably provide means for limiting the upward movement of the yoke with respect to the said stem and the cover, so that the cover may be raised by lifting the yoke. For this purpose, I am here showing the stem or tubular member as having'a shoulder 13 disposed for engaging the top of the yoke 10.

' To clamp the cover 3 tightly against the mouth of the receptacle when the hooks on the oke have engaged the projecting pins 2 on t e rece tacle, I provide means for raising the yo e withrespect to the cover, desirably in the form of a raising member mounted for rotation about the tubular stem. v This raising member, together with the tubular stem, the yoke and the means for limiting upward movement of the yoke preferably are mounted on the cover member so as to be retained in their relative operative dispositions, so that the resulting assembly can be manipulated as a unit when detached from the receptacle. For this purpose, I am here showing the raising member in the form of a lever 14 threaded on .a portion 15 of the riser stem above the cover 3. I am also showing a washer 16 interposed between the yoke, wish to be limited to the inclusion of a washer, since the latter operatively forms Y a part of either the yoke or the raisingmember in so far as the lifting action of the latter is concerned.

carries a handle 17 rotationally about member,

on the corresponding part 15 of the tubular member is such that the limited rotational 1 movement permitted by possible engagements of the handle 17 with the yoke 10 will still afford a suflicient lowering or lifting movement to the lever and the yoke for effecting a clamping or releasing of the cover.

en the cover member is detached from the cup or can, the lever carried by the cover member is in a lowered position, as that shown in dotted lines in Fig. 2, thereby permitting gravit to lower. the yoke so that the latter is out of engagement with the stop 13. then be slipped over the whereby it can be moved the axis of the tubular he cover can mouth of the receptacle and the hooks on the yoke can be brought into straddling relation raising member 14 and the bottom of the so as to reduce friction, but do not The lever 14 preferablyand the threading of the said lever to the'pins'2 (as shown in Fig. 5) by a partial rotation of the cover member on the receptacle. To facilitate this, I desirably provide means u on the cover member for preventing rotation of the yoke with respect to the cover, thereby permitting the cover to be rotated by rotational movement of the yoke and also permitting the user to grasp the yoke'for holding the cover from rotation while he is moving the thrust member. For these purposes, I am here'showing'the-cover as having a pair of edge lugs 18 between which one of the depending arms ll'on the yoke extends.

After the cover in the illustrated embodiment has been partially rotated so as to bring the hooks into operative relation to the projecting pins 12, the lever ,(or raising member) 14 is moved in a direction which L is counterlockwise in Fig. '2, namely, the direction in which the thread on the bore 15 causes the lever to move u wardly on thetubular member, thereby a ism raising the washer 16 and the yoke 10. Since the lower portion of each hook 12through its engagement with thec orresponding pin 2 resists a bodily lifting of the yoke, the result of this lifting action ofthe lcver with respect to the yoke or thrust'member is a depressing of the cover, thereby compressing the packing 4 and insuring a tight closure between the cover and thecan. When the container is to be opened, a movement of the thrust member in .the opposite direction releases this pressure, thereby permitting the cover -member to be rotated to bring the hooks out of alignment with the pins 2 and then allowing lShQ'COVGI' member to be lifted bodily off the receptacle.

In employing such a construction .in a spraying appliance, the stem member is desirably tubular and has an extension 20 reaching down into the cup 1 to a point near the bottom of the latter, and the stem member also desirably includes a union nut.2l swiveled on its upper end for making'a tight connection to the atomizing or spraying part of the appliance; the shoulder 6 and the nut 8 cooperate in sealing the tubular member with respect to the cover, and any gumming of the threads 7 will only tighten this seal. On the other hand, the threaded connection between the thrust member and the tubular member is not reached by the paint or other liquid in the appliance, so that this can not become ummed up. Hence I entirely avoid the difculties heretofore encountered with con-. tainers havin covers screwed on their cups, although emp oying a quite simple and easi- 1y manipulated ,construction and one in which the needed seal iseffected by the compressing of a cheap and easily replaced packing ring.

Since the variousconnections to the stem Hill Thus arranged,

as to form a discharge pipe for the receptacle.

Consequently, this bore is not likely to clog and can easily be cleaned" if necessary. So also, the parts attached to the stem member can easily be removed by merely detaching the nut 8 and then rotating the yoke on the cover. lVh'en thus rotated, the yoke engages the handle 17 on the cam lever and rotates the latter also, hence the yoke affords a lever for unscrewing the cam'lever, just as it also 7 affords a convenient handle for lifting the operativel cover member when loose or for normally lifting the entire appliance.

Broadly speaking, it will be noted that the raising member 14 is mounted for rotation about the axis of the stem member, which stem member is here shown as tubular; that the raisingmember is operatively interposed between two parts of the cover member, namely the stem member and the yoke or thrust member. One of the two parts between which the raising member is interposed-namely, the stem memberas the raising member threaded on it, so that rotation of the raising member moves the latter longitudinally of the stem. The other ofthe two parts between which the raising member is operatively inter- ,p0sed-namely, the thrust member (or yoke)has a shouldered engagement with 1 the raising member, which raising member is here shown in the form of a handled lever. Consequently, the said respectively threaded and shouldered engagements with the members between which the raising member is interposed cause a rotational movement of the raising member in one direction to lift the thrust member which is here pictured as a yoke.

However, while I have illustrated and described my invention in an embodiment in-.

cluding highly desirable details ofconstruction and arrangements, 1- do not wish to be limited to these, since many changes might obviously be made without departing either from the spirit of my invention on from the appended claims.
